1 All-in-One Storage Manager

All-in-One Storage ManagerHP StorageWorks All-in-One Storage Manager (ASM) is a storage hosting and management tool thatradically simplifies:

• Hosting storage for applications and shared folders, page 19• Configuring data protection, page 37• Managing storage, page 43• Monitoring storage, page 47

ASM provides storage-allocation wizards that walk you through the process of allocating and configuringstorage on your HP All-in-One Storage System to host application data and shared folders. Thestorage-allocation wizards also allow you to schedule backups and snapshots of hosted applicationdata and shared folders.

Other wizards are provided to help you set up SQL Server database storage, storage for user-definedapplications, and storage for shared folders.

ASM is designed to work seamlessly with Windows administrator tools, the HP All-in-One StorageSystem Management application, Microsoft iSCSI Target, and Data Protector Express. For example, youcan change your HP All-in-One Storage System’s:

• Storage allocations (quotas), shared folder permissions and names, and snapshot schedulesusing ASM, Windows administrator tools, and the HP All-in-One Storage System Managementapplications.

• Media rotation type using ASM and Data Protector Express.

However, you should not use Windows administrator tools to change the paths to storage configured onyour HP All-in-One Storage System or file directories created by ASM on application servers with storagehosted on your HP All-in-One Storage System. Doing so will break the iSCSI communication pathsbetween your application servers and HP All-in-One Storage System, and make it so ASM can no longerlocate allocated storage areas on your HP All-in-One Storage System.

Software requirementsASM comes preinstalled on your HP All-in-One Storage System. A license key is not required for ASM.

Software supportOnly storage for application servers running on Windows Server 2003 and on the same domain asyour HP All-in-One Storage System can be hosted.

ASM provides storage-management services for the following applications:


Table 2 Software support

Microsoft Exchange Server 2003 and 2007 See “Using the Host an Exchange Storage GroupWizard” on page 20.

File sharing services on local storage See “Using the Create a Shared FolderWizard” on page 21.

Microsoft SQL Server 2000 and 2005 See “Using the Host a SQL Server DatabaseWizard” on page 22.

User-defined applications See “Using the Host a User-Defined ApplicationWizard” on page 24.

Microsoft iSCSI Target and Data Protector Express are required to host application storage and createbackups using ASM. Microsoft iSCSI Target and Data Protector Express come preinstalled on your HPAll-in-One Storage System. A license key is not required for Microsoft iSCSI Target. Your license key forData Protector Express comes preinstalled on your HP All-in-One Storage System.

Storage management infrastructureThe purpose of ASM is to simplify storage management, so that you do not need to understand thecomplexities of allocating and configuring storage, and hosting application storage on your HP All-in-OneStorage System. ASM handles two types of use models:

• Managing storage for application servers, page 12• Managing storage for shared folders, page 13

Managing storage for application serversWith ASM, you can allocate, configure, and host storage for applications residing on servers thathost Exchange, SQL Server, and user-defined applications using the Host an Exchange Storage GroupWizard, Host a SQL Server Database Wizard, and Host a User-Defined Application Wizard.

The wizards suggest a default storage size, plus default advanced configuration settings, such as RAIDlevel, for each application component. You can customize all the defaults to fit your storage needs.However, the default advanced settings provided for Exchange and SQL Server are based on HP storage,Exchange, and SQL Server best practices and should generally not be changed.

For application storage, ASM creates an iSCSI LUN on your HP All-in-One Storage System for eachstorage group component, database component, or the user-defined application you select to host in thestorage-allocation wizard, and exports it to the application server whose storage will be hosted. ASMalso creates a LUN on your HP All-in-One Storage System to host the storage group component, databasecomponent, or the user-defined application you selected in the storage-allocation wizard. All storagecommunication passes through the iSCSI LUN on the application server to the LUN on your HP All-in-OneStorage System. This allows data saved by the application to the iSCSI LUN on the application server tobe automatically saved to your HP All-in-One Storage System instead (see Figure 1).


Figure 1 Application storage infrastructure

NOTE:The iSCSI communication path is transparent to the application, application server, and WindowsExplorer. The application, application server, and Windows Explorer believe the data is stored on theapplication server. So, to view the application data, you must navigate to the iSCSI LUN(s) on theapplication server, not the LUN(s) on your HP All-in-One Storage System, using Windows Explorer.

ASM provides automated data migration for Exchange and SQL Server. ASM discovers Exchangestorage group and SQL Server database components and hosts the storage components you selectthrough the storage-allocation wizards. ASM automatically migrates the data for the selected storagecomponents to your HP All-in-One Storage System. ASM also configures the application to read andwrite data for the hosted storage component to the iSCSI LUNs created on the application server by ASM.

ASM does not provide automated data migration for user-defined application servers. Youmust manually migrate the application data to your HP All-in-One Storage System after usingthe Host a User-Defined Application Wizard to allocate and configure storage space. See“Migrating user-defined application data to your HP All-in-One Storage System” on page 34 for moreinformation. You must also configure the application to read and write data to the iSCSI LUN created onthe application server by ASM. See the application’s documentation for more information.

Managing storage for shared foldersWith ASM, you can set up and monitor top-level shared folders (file shares) using the Create a SharedFolder Wizard. The wizard suggests a default storage size for each shared folder, plus default advancedconfiguration settings, such as RAID level. You can customize all the defaults to fit your storage needs.

For shared folder storage, ASM creates a LUN on your HP All-in-One Storage System to hold the sharedfolder and then creates the shared folder (see Figure 2). Shared folders whose storage is configured withthe same RAID level are created on the same LUN.


Figure 2 Shared folder storage infrastructure

ASM discovers any top-level and nested shared folders on your HP All-in-One Storage System duringsetup and afterwards on an ongoing basis. ASM allows you to monitor and manage any top-levelshared folders created on your HP All-in-One Storage System using ASM or other applications, such asWindows Explorer or the Shared Folder MMC snap-in.

After shared folders are created, communication between client and host takes place over the CommonInternet File System (CIFS) protocol.

Nested shared folders, which are shared folders that reside inside top-level shared folders, cannot becreated using ASM, but can be viewed in ASM by selecting the top-level shared folder in the contentpane and then clicking Properties in the Action pane. Use other applications, such as Windows Exploreror the Shared Folder MMC snap-in, to create nested shared folders on your HP All-in-One Storage System.

3. Click Next. This will open the Storage Allocation page. See Allocating space for components formore information on how to allocate space for components.


NOTE:The number of slots needed for your virtual library will depend on your tape storagesize. The number of slots backed up on your tape storage system and the number neededfor your virtual library will be the same.

Allocating space for componentsUse the Storage Allocation page in the wizards to specify the allocated space size and advancedconfiguration settings for each application component or shared folder listed. Default values are provided.

NOTE:15 MB is the minimum value that can be allocated. You cannot set the size below the minimum value.

NOTE:SQL Server and Exchange default advanced configuration settings are based on SQL Server orExchange, and HP storage best practices, and should generally not be changed.


• Click Next to accept the default values that ASM has provided for the components,user-defined application, or shared folder selected.

• Change the default size values:• Select a row to edit.• Highlight the storage size unit value and then enter a new value as necessary: megabytes

(MB), gigabytes (GB), or terabytes (TB).• Highlight the storage size number value and enter a new value, or click the arrow buttons

to change the value.

NOTE:The Size Range column shows the minimum and maximum storage space that can beallocated to each application component, user-defined application, or shared folder listed.Whenever you change the allocated space size or an advanced configuration settingfor an application component, the maximum value for Size Range is recalculated for allthe application components listed.

NOTE:To change the advanced configuration settings for an application component, user-definedapplication, or shared folder listed, select the item to edit and then click Advanced. See“Selecting advanced configuration settings” on page 27 for more information.

2. When you are done selecting the storage allocation and configuration settings, click Next to openthe summary page.


NOTE:After storage space is allocated and configured using a wizard, only the following storage configurationsettings can be changed:• Allocated space size• Percent full warning threshold• Enforce Allocated Limit (shared folders only)Once a logical disk is created, its configuration cannot be changed.

Selecting advanced configuration settingsUse the Advanced window in the wizard to change the allocated space size and default advancedconfiguration settings for each application component, user-defined application, and shared folder listed.

After storage is configured using a wizard, you can access the Advanced window from the AllocateSpace Wizard and change the allocated space size, percent full threshold warning, and/or enforceallocated limit (shared folders only) values as needed.

NOTE:When allocating storage on an AiO400 Storage System that does not have additional external storage,most of the default advanced configuration settings cannot be changed. This is because the AiO400Storage System is pre-configured with one volume and one logical disk, and ASM is unable to createany new logical disks on the system. All storage allocated is allocated from the existing logical disk.

Table 6 provides a brief description of the items you can modify:

Table 6 Advanced window items

Item Description Notes

SizeThe amount of storage that ASM allocatesto the application component, user-definedapplication, or shared folder you areconfiguring.

You are prevented from setting thesize below 15 MB.nl

NOTE:Once the allocated storagespace is full (100 percent used),no further data can be stored tothe space until you increase thesize using the Allocate SpaceWizard. The only exception isfor shared folders without anenforced allocated limit. If thereis unused storage space on thelogical disk where a sharedfolder without an enforcedallocated limit resides, data canbe written to the shared folderuntil the logical disk is full.

RAID LevelHard drive formatting that provides differentlevels of performance, capacity, and dataprotection.

For more information about RAIDlevels, see Customizing RAIDlevels on page 28.*

RAID Stripe Size

The number of bytes or kilobytes of data ineach RAID stripe (block of data). The RAIDstripe size selected affects performance.nl

For the best performance, select the stripe sizeclosest to the size of the files being saved.

ASM provides the followinggeneral values: small (8 kB),medium (16 kB), and large (64kB).*


Item Description Notes

Percent Full WarningThreshold

The percent full value that when reachedchanges the storage status to Warning andissues a warning alert. The warning indicatesthat storage use has surpassed the percentagefull value. For example, if you enter 75%, yousee a warning (yellow asterisk) in the contentpane when storage is at 75 percent full.

The percent full warning thresholdis set by default to 80%.nl

Percent full warning thresholdvalues are ASM-specific;percent full warning thresholdvalues selected in the QuotaManagement MMC snap-in arenot adopted by ASM. However, allother Quota Management MMCsnap-in settings are adopted byASM. See Setting a percent fullwarning threshold on page 30.

Exclusive Storage

Data is stored on hard drives dedicatedto storing only the data for the applicationcomponent, user-defined application, orshared folder you are configuring. The numberof hard drives dedicated depends on theallocated space size and other advancedstorage configuration settings selected for theitem you are configuring.nl

Exclusive storage is required by someapplications for the storage of specific typesof data.

For Exchange and SQL Server,ASM default values specifyexclusive storage for log files,which according to storage bestpractices, should be isolated fromother application storage areas.*

Enforce AllocatedLimit (Quota)

Sets an enforced quota for the amount ofstorage available to a shared folder. Whenthe storage space allocated to a shared folderis full, no further data can be saved to theshared folder.

This item is available for sharedfolders only. See Enforcing anallocated storage limit for sharedfolders on page 30.

Hot Spare Required

A hot spare is a hard drive reserved as a sparefor storage space configured as RAID 1, 1+0,5, or 6. A hot spare automatically replaces ahard drive when it fails. When the failed harddrive is replaced, its replacement becomes thenew hot spare.

A hot spare is assigned at thearray level. A LUN that doesnot require a hot spare may beassigned one anyway if anotherLUN on the same array requires ahot spare.

Physical Disk Type Type of physical disk to add for the hot spare

You are able to choose SAS,(Serial Attached SCSI) SATA,(Serial Advanced TechnologyAttachment) or SCSI (SmallComputer System Interface) for aphysical disk type.

*After you have allocated and configured storage for an application component, user-defined application,or shared folder using a wizard, you can change the allocated space size, change the percent full warningthreshold, and change the enforced allocated limit (shared folders only). However, you cannot changethe RAID level, RAID stripe size, Hot Spares, or Exclusive Storage settings. This is due to the nature ofhow hard drives work.

Customizing RAID levelsBefore you customize the default RAID level setting, review Table 7 to see how the different RAID levelsaffect performance, capacity, and data protection level.

Unless you customize the advanced configuration settings, the wizard configures the storage space withthe default values shown on the Advanced window:

• For Exchange and SQL Server, the wizard suggests default settings based on HP storage bestpractices and specific recommendations for Exchange storage group and SQL Server databasecomponents. You should generally accept these defaults.


• For user-defined applications and shared folders (where industry-standard recommendationscannot be determined), the wizard provides default settings you can customize.

Table 7 shows how the different RAID levels affect:

• Performance–The speed at which data is read from and written to the hard drives. The RAID levelwith the best performance rating provides the fastest reads and writes.

• Capacity–The available storage space on the hard drives. The RAID levels with the best capacityrating require the least amount of storage space to store data.

• Data protection–The number of hard drives that can fail without data being lost. The RAID levelwith the best data protection rating allows more hard drives to fail before data is lost.

For more information on the different RAID levels, see Table 7.

Table 7 Descriptions of RAID levels

RAID level Description

No RAID Offers no protection against disk failure. If a disk drive fails, datawill be lost.

RAID 0 – Striping (No Fault Tolerance)

Offers the greatest capacity and performance without data protection.If you select this option, you will experience data loss if a hard drivethat holds the data fails. However, because no logical drive capacityis used for redundant data, this method offers the best capacity. Thismethod offers the best processing speed by reading two stripes ondifferent hard drives at the same time and by not having a paritydrive.

RAID 1 – Mirroring

Offers a good combination of data protection and performance.RAID 1 or drive mirroring creates fault tolerance by storing duplicatesets of data on a minimum of two hard drives. There must be an evennumber of drives for RAID 1. RAID 1 and RAID 1+0(10) are the mostcostly fault tolerance methods because they require 50 percent ofthe drive capacity to store the redundant data. RAID 1 mirrors thecontents of one hard drive in the array onto another. If either harddrive fails, the other hard drive provides a backup copy of the filesand normal system operations are not interrupted.

RAID 1+0 – Mirroring and Striping

Offers the best combination of data protection and performance.RAID 1+0 or drive mirroring creates fault tolerance by storingduplicate sets of data on a minimum of four hard drives. There mustbe an even number of drives for RAID 1+0. RAID 1+0(10) and RAID1 are the most costly fault tolerance methods because they require50 percent of the drive capacity to store the redundant data. RAID1+0(10) first mirrors each drive in the array to another, and thenstripes the data across the mirrored pair. If a physical drive fails,the mirror drive provides a backup copy of the files and normalsystem operations are not interrupted. RAID 1+0(10) can withstandmultiple simultaneous drive failures, as long as the failed drives arenot mirrored to each other.

RAID 5 – Distributed Data Guarding

Offers the best combination of data protection and usable capacitywhile also improving performance over RAID 6. RAID 5 stores paritydata across all the physical drives in the array and allows moresimultaneous read operations and higher performance than dataguarding. If a drive fails, the controller uses the parity data and thedata on the remaining drives to reconstruct data from the failed drive.The system continues operating with a slightly reduced performanceuntil you replace the failed drive. RAID 5 can only withstand the lossof one drive without total array failure. It requires an array with aminimum of three physical drives. Usable capacity is N-1 where N isthe number of physical drives in the logical array.

RAID 6– Advanced Data Guarding(ADG)

Offers the best data protection and is an extension of RAID 5. RAID6 uses multiple parity sets to store data and can therefore tolerate upto 2 drive failures simultaneously. RAID 6 requires a minimum of 4drives and is available only if the controller has an enabler. Writer


RAID level Descriptionperformance is lower than RAID 5 due to parity data updating onmultiple drives. It uses two disk for parity; its fault tolerance allowstwo disks to fail simultaneously. Usable capacity is N-2 where N isthe number of physical drives in the logical array.

Setting a percent full warning thresholdTo receive a warning alert when storage capacity reaches a specified limit, set the percent full warningthreshold. You can set a warning threshold for any application component, user-defined application,and shared folder that ASM manages.

By default, the warning threshold is set to 80%. To change it, enter a new percent value on the Advancedwindow.

After you set a warning threshold, ASM changes the status indicator for the application component,user-defined application, or shared folder when this threshold has been surpassed. This is a warningonly; no hard limits are enforced on storage capacity as a result of setting this value. The warning isvisible in these places:

• A yellow warning icon appears on the application component, user-defined application, orshared folder icon in the content pane.

• As an alert in the Properties window.

NOTE:For shared folders, you can set an enforceable limit (or quota) for allocated storage, as well as a warningthreshold. For more information, see Enforcing an allocated storage limit for shared folders.

Enforcing an allocated storage limit for shared foldersASM provides a way to enforce an allocated storage limit for a shared folder. If enforced, the systemdoes not allow the amount of allocated space for the shared folder to be exceeded.

If the capacity of the shared folder surpasses the percent full warning threshold and reaches the allocatedspace limit, the file folder status changes from Warning to Critical in the content pane, and users areblocked from adding data to this shared folder.

NOTE:If you do not choose to enforce an allocated storage limit for a shared folder, the ASM status indicatorstill goes from Warning to Critical in the content pane; however, users are not blocked from adding datato the shared folder as long as there is still unallocated storage space on the logical disk where theshared folder resides. Data can be written to the shared folder until the logical disk is full.

By default, the Enforce Allocated Limit (Quota) is set to No for all shared folders. To change this setting,do one of the following:

• Using the Create a Shared Folder Wizard, change the Enforce Allocated Limit (Quota) settingon the Advanced window to Yes.

• Select the shared folder in the content pane, click Properties in the Actions pane, click theWarning Threshold tab, and then select the Enforce Allocated Limit (Quota).

• Select the shared folder in the content pane, click Allocate Space in the Actions pane, clickAdvanced, and then change the Enforce Allocated Limit (Quota) setting to Yes.

4 Managing storage

After an application is hosted or shared folder is created on your HP All-in-One Storage System using astorage-allocation wizard, you can manage its storage and data by:

• Increasing or reducing the allocated storage, page 43• Changing the percent full warning threshold, page 44• Removing application areas from view, page 44• Changing permissions, names, descriptions, or paths of shared folders, page 45• Deleting shared folders, page 45

Increasing or reducing the allocated storageYou can increase or reduce the storage allocated to an application component, user-defined application,or shared folder after storage is initially allocated and configured using a storage-allocation wizard.

Increasing the storage allocated requires ASM to grow the logical disk (increase the amount of hard drivespace allocated to the logical disk) holding the data. Reducing the allocated storage does not reduce thesize of the logical disk holding the data, because once hard drive space is allocated to a logical disk,it cannot be unallocated due to the configuration of hard drives.

NOTE:Unallocated storage on a logical disk is re-allocated by ASM when new or additional storage isallocated to an application component or shared folder and the advanced configuration values selectedfor the storage matches those of the logical disk.For example, if an application component or shared folder’s allocated storage is increased, anyunallocated space on the logical disk where it resides is used before the logical disk grows.

1. Select the application component, user-defined application, or shared folder in the content pane.

2. In the Actions pane, click Allocate Space to open the Allocate Space wizard.

3. Change the size value:

• Highlight the storage size unit value and then enter a new value as necessary: megabytes(MB), gigabytes (GB), or terabytes (TB).

• Highlight the storage size number value and enter a new value, or click the arrow buttonsto change the value.

The Size Range column shows the minimum and maximum storage space that can be allocated toan application component, user-defined application, or shared folder. Whenever you changethe storage space allocated to an application component or change an advanced configurationsetting for an application component, the maximum value for Size Range is recalculated for eachapplication component shown.

NOTE:To change the percent full warning threshold and/or enforce allocated limit (shared foldersonly) setting, click Advanced. See “Selecting advanced configuration settings” on page 27for more information.

4. Click Next to open the Review Tasks Summary page (see“Reviewing task summary and scheduling tasks” on page 33).


Changing the percent full warning thresholdYou can change the percent full warning threshold value for an application component, user-definedapplication, or shared folder after storage is initially allocated and configured using a storage-allocationwizard. See Setting a percent full warning threshold on page 30 for more information.

NOTE:For shared folders, you can set an enforced limit (quota) for allocated storage, as well as a warningthreshold. For more information, see Enforcing an allocated storage limit for shared folders on page 30.

To change the percent full warning threshold from the Properties window:


2. In the Actions pane, click Properties.

3. Click the Warning Threshold tab.

4. Change the percent full warning threshold value.

5. Click OK.

To change the percent full warning threshold using the Allocate Space Wizard:


2. In the Actions pane, click Allocate Space.

3. Click Advanced.

4. Change the percent full warning threshold value.

5. Click Next to open the Review Tasks Summary page (see“Reviewing task summary and scheduling tasks” on page 33).

Removing application areas from viewYou can remove application components and user-defined applications from view on the ASM userinterface. This allows you to remove storage information from the content pane pertaining to storageallocations lost due to hard drive failure or storage for an application component or user-definedapplication whose storage you plan to unhost.

Removing an application component or user-defined application from view does not unhost its storage.Its storage is still hosted on your HP All-in-One Storage System. To permanently remove storage fromyour All-in-One storage system, you must first remove the storage that is hosted by AiO. Dependingon the type of storage ,see http://h71028.www7.hp.com/ERC/downloads/4AA1-1026ENW.pdf forinformation on how to remove different types of storage.

NOTE:If you remove an application component or user-defined application from view without unhosting thestorage, your All-in-One Storage System will re-discover the applications immediately.

NOTE:This action is not available for shared folders. Because ASM automatically discovers top-level sharedfolders on your HP All-in-One Storage System, the folder would just reappear after the next discoveryprocess. A shared folder is automatically removed from view when it is removed from your HP All-in-OneStorage System.

To remove an application component or user-defined application from view:

44 Managing storage

http://h71028.www7.hp.com/ERC/downloads/4AA1-1026ENW.pdf

You can find the advanced configuration settings and capacitiesof unused (and used) logical disks on the Properties window for each logical disk (seeAccessing properties for HP All-in-One Storage System logical disks on page 59).


6 Troubleshooting, servicing, andmaintenance

Troubleshooting the storage systemUse the references and general guidelines in this section to troubleshoot your HP StorageWorks All-in-OneStorage System.

Operating system problems and resolutionsUse the suggestions below to help resolve operating system issues.

Table 31 Operating system problems

Problem Action

Operating system locks up Scan for viruses with an updated virus scan utility.

General protection fault (GPF) occurs. This can occurwhen the Microsoft operating system terminatessuddenly with an error, including, but not limited to:• Miscalculating the amount of RAM needed for

an allocation• Transferring execution to a segment that is not

executable• Writing to a read-only or a code segment• Loading a bad value into a segment register• Using a null pointerA GPF is immediately identifiable by a blue screenwith white text, and the text may contain informationthat identifies the problem.

• Remove any newly installed software or hardwareto verify that they are not the cause.

• Boot the server in Safe Mode or the last knowngood configuration.

If neither of these actions resolves the problem, contactan authorized service provider. For more informationabout debugging tools or specific GPF messages, seethe Microsoft web site: http://www.microsoft.com/whdc/devtools/debugging/default.mspx.

Errors are displayed in the error log Follow the information provided in the error log, andthen see the operating system documentation.

Operating system updatesUse care when applying operating system updates (service packs, hotfixes, and patches). Beforeupdating the operating system, read the release notes for each update. If you do not require specific fixesfrom the update, HP recommends that you do not apply the updates.

If you decide to apply an operating system update:

1. Perform a full system backup.

2. Apply the operating system update, using the instructions provided.

3. Install the current drivers.

Application software problemsIf your application software locks up, perform the following actions:

• Check the application log and operating system log for entries indicating why the software failed.• Check for incompatibility with other software on the server.


http://www.microsoft.com/whdc/devtools/debugging/default.mspx

http://www.microsoft.com/whdc/devtools/debugging/default.mspx

• Check the support web site of the software vendor for known problems.• Review the log files for changes made to the server that may have caused the problem.• Scan the server for viruses with an updated virus scan utility.

SQL Server errors

Host a SQL Server Database Wizard authentication error

Problem: While using the Host a SQL Server Database Wizard, you receive an error message informingyou that ASM cannot authenticate with the server that hosts SQL Server.

Solution: Each SQL Server license (instance) must have a login for the local user called ASMUser with theserver role defined as System Administrators. This login is created during the installation of the ASMagent on the server that hosts SQL Server; however, if another SQL Server license is installed after theASM agent is installed, this login will not be configured.

To fix this problem, you can remove the ASM agent from the server that hosts SQL Server, and thenreinstall it following the instructions in the HP StorageWorks All-in-One Storage System quick startinstructions (no information will be lost). Or, manually enter the login as follows:

1. Open SQL Server Enterprise Manager.

2. Connect to the server with SQL Server data you want to store on your HP All-in-One Storage System.

3. Select the Security Folder.

4. Select Logins.

5. Select New Login.

6. In the Name field, enter ASMUser.

7. In the Domain field, enter the domain name for the server that hosts SQL Server.

8. Select the Server Roles tab.

9. Select the System Administrators server role and click OK.

ASM alertsASM generates an alert whenever the status of an application area or storage area changes from OK toWarning or Critical. The alerts describe the condition that caused the storage status to change.

Alerts are displayed on the General tab of the Properties window.

66 Troubleshooting, servicing, and maintenance

Figure 3 Example of alert

To view alerts:

• Select an item in the Content pane and click Properties in the Actions pane to view the alertsfor the item selected.

Storage status is displayed as an icon when the storage status is Warning or Critical:

• In the Content pane on application, application component, or logical disk icons.• In the Properties window on the General tab.

NOTE:ASM rolls up any status alert to the highest level. For instance, if a shared folder has surpassed itspercent full warning threshold and exceeded its allocated storage space, a warning icon is shown onthe shared folders icon. Likewise, if a critical status exists in an Exchange mail store, the critical icon isalso shown on the Exchange storage group icon.

Table 32 on page 68 lists all possible ASM alerts and provides descriptions, possible causes, andsolutions for each alert.

Recovering from logical disk failureApplication component or shared folder data stored on a logical disk that failed is lost. To recoverthe data and reallocate storage on your HP All-in-One Storage System, replace any failed harddrives, allocate new storage on your HP All-in-One Storage System using a storage-allocation wizardto replace the lost storage, and then restore the data to the new allocated storage using a backup(see “Restoring data from backups” on page 40).

NOTE:Snapshots cannot be used to recover data lost as a result of logical disk failure. Snapshots of Exchangestorage groups, SQL Server databases, user-defined applications, and shared folders are stored on thesame logical disks as the original data, and therefore are also lost.


Glossary

This section defines the terms used to describe the ASM user interface and program features.

Actions pane The right pane in the main window of the ASM user interface that provides alist of actions, based on your current selection in the Content pane. Along withother selectable items, the Actions pane provides access to storage-allocationwizards, which help you allocate and configure storage.

Advanced window A window accessed by clicking the Advanced button in any of thestorage-allocation wizards or the Allocate Space Wizard. When accessedfrom any of the storage-allocation wizards, the Advanced window allows youto change the size of the allocated space and the default (recommended)advanced configuration settings. When accessed from the Allocate SpaceWizard, the Advanced window allows you to change the size of the allocatedspace, percent full warning threshold, and enforced allocated limit (sharedfolders only).

allocated space Storage space that is being used by, or reserved for, application or sharedfolder storage.

application server A server computer in a computer network dedicated to running certain softwareapplications whose job is to provide network access to software client/serverapplications and, sometimes, the data that belongs to applications as well.

array Also known as a JBOD (just a bunch of disks). A group of hard drives in anenclosure (chassis) that are controlled by an array controller.

array controller Controls reads and writes to the hard drives in an array.

backups A read-only copy of data copied to media, such as hard drives or magnetictape, for data protection.A full backup copies all the data selected to be backed up. An incrementalbackup copies only data selected to be backed up that has changed since thelast full backup.Backups provide data protection in the event of system or hard drive failure,because the data is stored on media separate from the system hard drives.

backup applica-tion

An application used to create, manage, and monitor backups.

CIFS Common Internet file system. The protocol used in Windows environments forshared folders.

Content pane The center pane in the main window of the ASM user interface that displaysstorage utilization, and the storage status of application components and sharedfolders.

data migration The process of moving data from one storage device to another, such as movingapplication data from an application server to your HP All-in-One StorageSystem. ASM supports automatic data migration for Exchange and SQL Serverdata.

data protection Protects data from being corrupted or lost as a result of hard drive failure.Methods used to provide data protection include RAID and backups.


enforce allocatedlimit (quota)

An enforced quota for the amount of storage available to a shared folder. Anenforce allocated limit prevents data from being saved to a shared folder onceall the storage space allocated to the shared folder is used.

Exchange storagegroup

The fundamental unit of storage management in Microsoft Exchange. Storagegroups consist of Mail stores, Public stores, and log files.

exclusive storage An Advanced window option that allows you to dedicate a hard drive(s) forstoring data for a specific application component or shared folder.

file system A method for storing and organizing computer files and the data they contain tomake it easy to find and access them.

hot spares An Advanced window option that allows you to reserve one or two hard drivesas spares. A hot spare is a hard drive reserved as a spare for storage spaceconfigured as RAID 1, RAID 1+0(10), or 5. A hot spare automatically replacesa hard drive when it fails.

iSCSI Internet small computer system interface. Like an ordinary SCSI interface, iSCSIis standards-based and efficiently transmits block-level data between a hostcomputer (such as a server that hosts Exchange or SQL Server) and a targetdevice (such as an HP All-in-One Storage System). By carrying SCSI commandsover IP networks, iSCSI is used to facilitate data transfers over intranets and tomanage storage over long distances.ASM works with the Microsoft iSCSI Target, which builds the iSCSI infrastructureon application servers with data hosted on your HP All-in-One Storage Systemand on your HP All-in-One Storage System so that application data is stored onyour HP All-in-One Storage System.

iSCSI LUN A type of LUN (logical disk) created on an application server by ASM when astorage-allocation wizard is ran to host application storage. When applicationstorage is hosted using ASM, all storage communication passes through theiSCSI LUN on the application server to the LUN on your HP All-in-One StorageSystem. This allows data saved by the application to the iSCSI LUN on theapplication server to be transparently stored on your HP All-in-One StorageSystem instead.

log file The component of a Microsoft Exchange storage group or a Microsoft SQLServer database that contains log data.

logical disk Also known as a LUN. A logical disk contains one or more volumes and spansmultiple hard drives in an array. RAID configuration of storage is performed atthe logical disk level.

LUN Also known as a logical disk. ASM will grow a LUN (make it larger) when theLUN requires more of the storage space on an array.

Mail store The component of a Microsoft Exchange storage group that contains mailboxdata.

Menu bar The horizontal menu located at the top of the ASM user interface. The menu baris the Microsoft Management Console menu bar; ASM is a snap-in hosted bythe Microsoft Management Console.

MMC snap-in Microsoft Management Console snap-in. An application added to the MicrosoftManagement Console. All-in-One Storage Manager is a MMC snap-in.

NAS Network-attached storage. This term is used to refer to a specialized type offile server. The HP All-in-One Storage System provides NAS storage as wellas iSCSI storage.

74 Glossary

Navigation pane The left pane in the main window of the ASM user interface that allows youto quickly navigate between HP All-in-One Storage System Managementapplications.

NFS Network file system. The protocol used in most Unix environments to sharefolders or mounts. The Create a Shared Folder Wizard does not create NFSshares, but NFS shares can be created using the Shared Folder MMC snap-in.

percent full warn-ing threshold

Percentage of capacity for a storage area (storage allocated to an applicationcomponent or shared folder) at which an alert is generated. This alert isdisplayed in the Content pane and sent to the Windows Event Log. SeeSetting a percent full warning threshold on page 30 for more information.

Public store The component of a Microsoft Exchange storage group that contains publicfolder data.

RAID Redundant array of intelligent disks. Two or more hard drives configured toprovide a storage with resilience to hard drive failure through the use of RAIDstriping and parity disks.

RAID level See Table 7 for RAID level descriptions.

RAID striping Writing data to hard drives in an array by interleaving bytes or groups of bytesacross the multiple hard drives. This allows more than one disk to be read fromor written to simultaneously, which increases the performance.

RAID stripe size The number of bytes or kilobytes of data in a RAID stripe (block of data).

restore To recover lost data using a backup.

revert To return stored data to a previous state using a snapshot.

scaling Changes the display proportions of application component and shared folderstorage in the Content pane. You can choose to scale by the size (capacity) ofthe application component and shared folder’s storage space, or scale them allthe same. To change the scale setting, select Tools > Options.

size The amount of storage that ASM allocates and configures for an applicationcomponent or shared folder. To change the size of the allocated storage foran application component or shared folder, select the application componentor shared folder in the Content pane and then select Allocate Space in theActions pane.

snapshot A read-only copy of a volume at a specific point in time. Unlike a backup, datais not copied to any media during a snapshot. Instead, when a file is modifiedafter a snapshot is created, the new updates are written to a new location. Thefile-system maintains records and pointers to keep track of the snapshot dataand file changes. A snapshot takes less than a second to create.

Status bar The area located at the bottom of the ASM user interface that displays serverinformation and system alerts.

tape library An enclosure filled with magnetic tape cartridges, tape drives, and a robot(s).The tapes are electronically labeled for identification and stored in library slotswhen not in use. When data needs to be written or read from a tape, the robotloads the tape cartridge into an available tape drive in the library.

Task Viewer A window that displays completed tasks, scheduled tasks, and errors. To openthe Task Viewer, select Tools > Task Viewer.

toolbar The area below the menu bar that contains icons for commonly-used commands.The toolbar is the Microsoft Management Console toolbar; ASM is a snap-inhosted by the Microsoft Management Console.


top-level share Top-level shared folder in a directory hierarchy.

unallocated space Unused storage that is not allocated. Unallocated space includes raw(unconfigured) storage and unused configured storage (logical disks).

user-defined ap-plication

Any remote application that runs under Windows Server 2003 and uses NTFSvolumes for storage.

virtual array Hard drives in an array can be divided into groups to create two or more virtualarrays. ASM grows a virtual array (makes it bigger) when a hard drive(s) mustbe added to the virtual array to obtain the required storage space. A virtualarray contains one or more LUNs.

virtual library Also known as a virtual tape library. A virtual library acts like a physical tapelibrary except that hard drive arrays are used for storage instead of magnetictapes.

volume Resides on a logical disk. Volumes are assigned a drive letter on the file systemand contain file directories.

warning threshold See percent full warning threshold.
